Re: x apps cant start from bash

[<dwilson4life at yahoo dot com>]

Set you DISPLAY variable to an IP address that your
remote application can connect to, followed by setting
up your X server access control program (xhost) to
allow remote connections from all hosts (xhost +) or a
particular host (xhost + <remote server hostname or IP
address).

Hope that this helps.
